It consists of three phases or stagesto be executed by a battery charger. As a result of the current, the battery absorbs the charge and its voltage rises. During this phase, the charge current decreases gradually to a small residual value that compensates for any self-discharge of the battery. For the alternating-current system, see Three-phase electric power.

Retrieved from ” https: Stage 2 is called the U o -phaseconstant-voltage boost stageabsorption stageor topping charge. The voltages in the U and U o phases stages 2 and 3 depend on the type of battery and the temperature. The decrease is imposed by the battery. The charging current is a compromise between charging time favoring high currentsthe prevention of damage due to overheating or gassing favoring low currentsand cost of the charger favoring low currents.

IUoU battery charging

417773 Stage 1 is called the I-phaseconstant-current stageor bulk charge stage. If a battery is connected to a significant load during charging, the end of the Uo-phase may never be reached and the battery will gas and be damaged, depending on the charge current relative to the battery capacity.

The battery capacity C is expressed in Ah units, typically the C 20 dun based on a hour discharge time. The charger provides a constant current, typically the maximum current that the charger is capable of producing.

IUoU battery charging – Wikipedia

The dln in the U o -phase is too high to be applied indefinitely hence, overvoltagebut it allows charging the battery fully in a relatively short time. This phase occurs when an IUoU charger is connected to a deeply discharged battery.

Views Read Edit View history. Stage 3 is called 4773 U-phase or float charge statethe voltage is reduced to a value that is safe to be applied for long periods weeks without significantly reducing the lifetime of the battery. IUoU is a DIN -designation [1] DIN for a lead-acid battery charging procedure that is also known as 3-stage charging3-phase chargingor 3-step charging. In practice, it depends on the capability of the charger.

This page was last edited on 24 Mayat The current in the I-phase stage 1 should be chosen depending on the capacity of the battery. Diin have varying numbers of cells typically six for an automotive battery and may be flooded-cell, absorbed-glass-matt AGMor gel-electrolyte types. The charger limits the maximum voltage to U maxa dij or temperature-dependent maximum, typically around 2. In this stage, the battery is continued being charged at a constant over voltage U obut the charge current is decreasing.

The U o -phase is concluded when the charge current goes xin a threshold I minafter which the U-phase is entered.

A bad battery will have short I-phase and Uo-phase, but there is a risk of gassingfurther damaging the battery. The purpose is to fully charge the battery in a relatively short time without reducing its life span and to indefinitely keep the battery charged as long as the charger is connected. The three phases are: The voltage U o may be the same 14773 U max in the previous stage, or it may be taken slightly higher.
